Reloading Question

[SecondAmendment]

I'm reloading for 9mm using a 147 gr. Rainier (TMJ) and 3.4 gr. of Tite Group. I was only able to get CCI magnum small pistol primers #550. Will this pose any pressure problems using these primers instead of #500 non magnum. What I've read seem to say OK in about 75% of info read. Thanks..

will be fine, don't go up to max powder charge tho. stay down scale some.

I do not load 147 grain but do load 125 grain lead. I use Accurate No. 2
and it has a load range of powder. I use the low figure with magnum primers and get a zippy round. If tite group has a powder range definitely start with the low figure when using magnum primers.
If only a maximum charge is given start with 10 per cent less.

The load of 3.4 gr. of titegroup is the dead middle of the published load.

The magnum primers shouldn't matter. Just make sure that you don't seat the bullet too deeply and use a good taper crimp.
